Description

FIELD

The present disclosure relates to systems, methods and devices for controlling display elements, and more particularly to presentation of automatic subtitle display for display devices and vehicles.

BACKGROUND

Media content typically includes sound in a single language. Sometimes, audio data for the media content is dubbed such that additional or supplementary recordings replace the original production sound in a post-production process. Dubbing sound for media content can be labor intensive. In addition the sound quality of the media is often reduced. For many types of media, viewers desire the ability to understand voice or speech of the media. Some broadcast formats include secondary audio accompanied with the media and the media player can be set to include subtitles. There exists a need to provide display devices with additional subtitle information not limited to a fixed set of subtitle information provided with the media.

Many display devices are not configured to provide content other than information that is received by an input. Conventional display devices are usually programmed for a particular set of operation languages. There is a desire to provide display devices with the ability to access and present media with a desired language.
